October 28, 2020 · NOAA Storm Events record
Event narrative (NOAA)
Jefferson Parish ordered a mandatory evacuation for coastal communities including Grand Isle, Jean Lafitte, Crown Point and Barataria. The storm surge breached the local levee on the gulf side of Grand Isle. High water marks collected by the NWS suggest peak water levels of 2 to 3 ft inundation across much of the island. This is consistent with the peak water level recorded by the NOS tide gauge on Grand Isle at 2.98 ft MHHW. The Barataria Bay (NGIL1) tide gauge measured a peak of 7.81 NAVD88. The Barataria Bay (EGIL1) tide gauge measured a peak of 3.74 NAVD88. The Caminada (CPGL1) tide gauge measured a peak of 3.58 NAVD88.
